Gawd, I just love Bubble Bobble. I really do. It's such a deliciously cute lil' game... Made the mistake of getting it for MAME... Hoooooooooooooboy was that a fun three hours~ X3

Anywho, first ones that came to mind (that were feasibly bubbledragonifiable).. Myself (Red),  jagaz (Green),  wildside and  gamerwords (Brown)

Yeah, I honestly don't care that these suck, I just wanted to get this outta my head. XD
... And gamerwords looks slightly like Ludwig Von Koopa, the way I've drawn him.. D:
